The resulting complex can then latch onto viral DNA carrying the spacer sequence, calling forth an enzyme that cuts and disables that DNA. The enzyme, called "CRISPR-associated protein 9," or Cas9, is essentially a pair of molecular scissors. There are alsoother types of Cas enzymesthat can ...
You might only get sick once or twice a year, but that's because your immune system is on constant alert. There are many defenses that germs have to penetrate in order to get inside where they can wreak the most damage. Tears and mucus contain an enzyme that break...

A second set of instructions, based on Nobel Prize winning work. deactivates the CTLA-4 signaling molecule. This molecule, produced by cancer cells, stops T-Cell activation. Deactivating these signaling molecules enables T-Cells to do a much better job of attacking pathogens and cancer cells. A...
So how do I stop potatoes from turning brown? Of course, if you're throwing that peeled potato straight into a pot of boiling water, that creamy color will stay frozen in time because heat deactivates the browning enzymes. But for most of us, prepping for an enormous family feast means...

Does phosphorylation activate or deactivate? The phosphorylation of a proteincan make it active or inactive. Phosphorylation can either activate a protein (orange) or inactivate it (green). Kinase is an enzyme that phosphorylates proteins. Phosphatase is an enzyme that dephosphorylates proteins, effecti...
enzyme. There are a couple of ways of preventing this activity. One is to block the action of aromatase using drugs such as Armidex or Cytadren. Another is to take a drug that deactivates or destroys the enzyme itself. An alternative and arguably superior anti-estrogenic treatment would be...
Adding the enzyme lactase to milk, which essentially predigests the sugar intoglucoseandgalactose. The resulting milk still contains the enzyme, so it is ultrapasteurized to deactivate the enzyme and extend the shelf life of the milk. Passing milk over lactase that is bound to a carrier. Using...
